| 20100008114 | DISCONTINUOUS PROTECTION METHOD FOR CLAMPING CURRENT IN INVERTER - A discontinuous protection method clamps phase currents in an inverter initially sets a current clamping flag and a current threshold. The phase currents are alternatively cut out by a criterion based on the current-clamp flag and based on whether the phase currents exceed the current threshold. By proving current in discontinuous way under certain situation judged by the criterion, over current protection and shut-down of inverter can be prevented. The method further sets a carrier frequency modulation flag. The carrier frequency is increased to 8 KHz when the phase current is to be cut out, thus speeding up protection for clamping current. | 01-14-2010 |
